I don't quite follow. People don't go on Google and search for midieval history and pretend they wrote the Wikipedia article on it because they found it on Google.
People _do_ use LLMs to make art in someone else's style (knowingly or unknowingly) and claim it as their own creation.
Also, I wouldn't say the creators of LLMs are competing with artists. The users of LLMs are. Arists don't make LLMs, they make art, and people who use midjourney and such make art.
But I'd argue that creators of LLMs are still liable for the harm people cause using their tools. Perhaps not legally, but certainly ethically.
